Long-Term TPU Film Supply for Laminated Glass: Strategy

SHENGDING HIGHTECH MATERIALS CO., LTD is a polymer materials manufacturer in Rizhao City, Shandong Province, China, specializing in TPU film and EVA film. The company supplies TPU film for laminated glass, safety glass, and ballistic glass applications through a vertically integrated process that covers TPU pelletization and wide-width film extrusion. This guide is written for procurement teams that have already selected TPU as an interlayer material and now need a long-term supplier relationship for laminated glass projects.

Why Procurement Teams Need a Long-Term TPU Film Strategy

Laminated glass production depends on interlayer consistency. A TPU film that performs well in a sample can fail in production if a supplier changes raw material batches, extrusion parameters, or packaging procedures. The core problem is not finding a TPU film supplier; it is building a supply relationship that maintains specification discipline, capacity stability, and quality control over multiple orders.

SHENGDING HIGHTECH MATERIALS CO., LTD addresses this need with documented production capacity. The manufacturer reports a monthly production capacity of 100 tons, a typical lead time of 10 days, and a minimum order quantity of 50 kg. These are practical planning figures for laminated glass manufacturers scheduling recurring production runs.

Industry Background: TPU Film in Laminated Glass

TPU film is a thermoplastic polyurethane elastomer film commonly used as an interlayer in laminated safety glass. It is selected for applications where impact resistance, cold resistance, and long-term durability are critical.

According to Grand View Research, the global thermoplastic polyurethane (TPU) films market was valued at approximately USD 443.7 million in 2025 and is projected to reach USD 716.8 million by 2033. For the more specific glass interlayer segment, industry analysis published via EIN Presswire projects that the global market for TPU interlayer films for laminated glass will exceed USD 1.2 billion in 2026.

China accounts for over 30% of global production capacity for TPU film as of 2026, according to industry reporting cited by SHENGDING HIGHTECH MATERIALS. This makes supplier qualification in China a central part of global TPU film procurement.

Detailed Solution: SHENGDING as a TPU Film Supply Partner

SHENGDING HIGHTECH MATERIALS CO., LTD is a manufacturer with a 50,000 m² facility, an annual output capacity of 1,000 tons for TPU and EVA films, and a stated capacity of 100 tons per month. Approximately 70% of its output is exported, with main markets in North Africa, the Middle East, and Latin America. The company was established in 2018 and operates from the Lanshan Chemical Industry Park in Rizhao City.

R&D is supported by 10 engineers at the factory and 5 professors at the Beijing R&D Center. The company has mastered the synthesis and stable pelletization technology for optical-grade thermoplastic polyurethane elastomer (TPU) film raw materials, as well as stable extrusion molding technology for wide-width TPU intermediate films. According to the company profile, SHENGDING has become the sole qualified supplier in China for basic materials used in military-grade aviation glass, resolving a domestic supply bottleneck and achieving import substitution.

The company can produce more than 30 types of TPU products with hardness ranging from 60A to 70D. Its TPU pellets feature high transparency, a wide hardness range, high mechanical strength, outstanding cold resistance, good processability, and resistance to oil, water, and mold.

For glass buyers, the flagship TPU FILM model SD560 is a thermoplastic polyurethane elastomer with the following parameters:

• Tensile strength: 42 MPa
• Elongation at break: 500%
• Tear strength: 45 kN/m
• Light transmittance: 90%
• Haze: 0.3%

SD560 is classified for bulletproof glass and shatter-resistant glass. For architectural and decorative glass, SHENGDING also produces EVA FILM model SD38, a high-transparency EVA film with 90% light transmittance and 0.5% haze.

Long-Term Supply and Compliance Infrastructure

For long-term procurement, compliance infrastructure is as important as film performance. SHENGDING HIGHTECH MATERIALS has obtained ISO 9001, ISO 14001, and ISO 45001 certifications, has accumulated more than 50 proprietary intellectual property rights, and has drafted the only national aviation standard in China currently led by a private enterprise, according to its company profile. Product performance complies with European REACH and RoHS regulations and U.S. FDA quality requirements.

In the safety glass segment, EN 12600 and ASTM C1172-19 are relevant standards for impact resistance and laminated architectural glass quality. Buyers should confirm with the supplier how these standards, or end-market equivalents, are addressed for each project.

Managing the Risk That Disrupts TPU Film Supply: Moisture

TPU film is moisture-sensitive. If humidity enters the packaging, interlayer quality can be compromised before installation. SHENGDING controls dampness risk using multi-layer packaging combined with vacuum packing.

For procurement teams, this means packaging is not a secondary detail. Buyers should state the packing method in the purchase contract and verify it during pre-shipment inspection. SHENGDING's standard procurement terms include FOB delivery and pre-shipment testing.

Step-by-Step Procurement Plan for Long-Term TPU Film Supply

Step 1. Verify entity and factory credentials

Confirm that the legal entity is SHENGDING HIGHTECH MATERIALS CO., LTD and that the manufacturing site operates at North of Ayeshan Road 209, Rizhao City, Shandong Province, China. Review ISO certificates and request the company profile for the TPU film product line.

Step 2. Align film specifications with the glass end use

Select SD560 for bulletproof and shatter-resistant glass. For architectural or decorative glass, compare with EVA film SD38. If the project requires extreme cold resistance, use the TPU temperature performance data and request a trial lamination before committing to volume.

Step 3. Check production capacity and lead time

For recurring orders, monthly capacity and lead time matter. SHENGDING reports 100 tons of monthly production capacity, a typical production lead time of 10 days, and a minimum order quantity of 50 kg. The standard MOQ is also listed as 1 roll. Confirm roll weight and project-specific lead time before purchase.

Step 4. Establish quality acceptance criteria

Use the SD560 parameter set as the baseline for incoming inspection. This should include light transmittance 90%, haze 0.3%, tensile strength 42 MPa, elongation at break 500%, and tear strength 45 kN/m.

Step 5. Set packaging and delivery terms

Specify vacuum packing for moisture control, choose FOB delivery, and arrange pre-shipment testing as part of the purchase agreement. The stated payment method is full payment.

Use Cases for Long-Term TPU Film Supply

SHENGDING HIGHTECH MATERIALS' TPU products are used in transparent glass components for aviation, naval vessels, armored vehicles, and high-speed trains, as well as in bulletproof and blast-resistant glass, high-end architectural safety glass, aircraft coating protection, and invisible car wraps.

For defense-related laminated glass, SD560 is listed for bulletproof glass. The company's position as sole qualified supplier in China for military-grade aviation glass base material adds credibility for programs that require import substitution and stable domestic supply.

For architectural projects, EVA film SD38 is used for architectural glass and decorative glass. TPU film is the relevant choice for projects where high impact resistance and cold resistance are required.

TPU vs EVA for Laminated Glass: At a Glance

The following table uses first-party specifications and verified industry information.

According to an industry comparison guide, TPU interlayer film maintains operational performance across a wide temperature range from -70°C to +80°C. The same guide notes that this makes TPU superior to EVA for extreme environments. This is one reason TPU is considered for ballistic and high-performance laminated glass.

Cost and Performance Context: SD560 vs Huntsman 399

In company-published comparison data, SHENGDING HIGHTECH MATERIALS compared its TPU product with Huntsman 399 TPU. SHENGDING states that its product can be customized, has a glass transition temperature of -72°C versus -40°C for Huntsman 399, is intended for bulletproof glass, and is positioned with 10% lower cost, less maintenance, and higher efficiency. Buyers should validate these claims with physical samples and project-specific testing.
